Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496912, here are decompositions:

  • 103 + 31496809 = 31496912
  • 193 + 31496719 = 31496912
  • 241 + 31496671 = 31496912
  • 313 + 31496599 = 31496912
  • 373 + 31496539 = 31496912
  • 463 + 31496449 = 31496912
  • 523 + 31496389 = 31496912
  • 541 + 31496371 = 31496912

Showing the first eight; more decompositions exist.
